It also enables the auto-configuration feature of Spring Boot. Author: Ramesh Fadatare Spring Annotations Spring Boot In this quick article, we will discuss Spring boot annotations with examples. You can run them just like you can run the main class in Java, this annotation is used to annotate the main class of your Spring Boot application. Since Spring Boot allows you to execute your Web application without deploying it into any web server like Tomcat. Without wasting any more of your time, here is my list of some of the useful Spring Boot annotations which every Java developer using Spring Boot should be familiar is the most common Spring Boot annotation and you will find it probably in every single Spring Boot application. Annotations in Spring Framework Similar to other places, annotations help by providing metadata and instructions to the Spring container. I'll just provide a quick overview with an example for the sake to keep this article short but you join Learn Spring Boot in 100 Steps course to learn them in depth with more real-world examples.ĥ Spring Boot Annotations Every Java Developer should know In order to bridge this gap, I am going to share some of the essential Spring Boot annotations every Java developer should be familiar with. Even small information that what does the particular annotation does and when to use them will go a long way in improving your understanding of the code you write or read. Well, nothing is bad, as long as you know what you are doing but just learning a bit of fundamentals never hurt. They just copy-paste the code without giving much thought.įor example, the annotation is required for most of the main class you write with Spring Boot, hence, most of the Java developers end up just copy-pasting the whole class and trying to customize it for their own need. There are many advantages of Spring Framework. makes the code loosely coupled so easy to maintain makes the code easy to test Advantages of Spring Framework. We provide metadata to the IOC container either by XML file or annotation. When I think about Java, some of the essential annotations which come to our mind are and Similarly, if you are using the Spring Boot framework, an extension of the Spring framework which aims to simplify the Java development with Spring, you will often end up using a couple of annotations like or Java developer just blindly uses annotations without knowing that what they are and what they do. In Spring framework, IOC container is responsible to inject the dependency. They provide a lot of value and that's why it's important for a Java developer to get familiar with essential annotations of the framework he or she is using. It's now impossible to write any Java code without using annotations but that's for good. They all act the same because they are all composed annotations with Component as a meta-annotation for each of them. Hello guys, if you are coding in Java for long then you know that Annotations have completely changed the way you write Java code. Spring has provided a few specialized stereotype annotations: Controller, Service and Repository.They all provide the same function as Component.
